(Closed) Can my mom be my Matron of Honor?

So my fiance has one more groomsman than I have bridesmaid. Okay, okay, he has two groomsmen and I have a maid of honor. I have three sisters, but I feel like I can’t just pick one sister. Would it be cheesy or weird if I ask my mom to be my matron of honor?? Are there things I should be considering that I’m not thinking about? What do you ladies think??
